Abstract
An improved insulated cover is provided for removable mounting onto a spa or hot tub or the like to minimize thermal and evaporative losses, while additionally safeguarding against foreign objects and/or persons falling into the tub. In the preferred form, the insulated cover comprises an outer frame ring defining a radially outwardly projecting rim, in combination with a structural membrane stretched across the frame ring with a peripheral margin of the membrane wrapped over the outer rim and radially constricted for retention thereon by a drawstring or the like. The frame ring and structural membrane cooperatively define an upwardly open pocket for receiving and supporting a selected insulation material. A flexible decorative top sheet is stretched across the frame ring to close the insulation pocket, wherein a peripheral margin of the decorative top sheet is wrapped over the outer rim and radially constricted for retention thereon by a drawstring or the like.
